When looking at the Symantec Management Agent UI, the Managed Deliver Policies (SWM) or Software Update Policies (SWU) do not appear to be listed.
ITMS 8.x
Policy requests from clients seems to filter out SWM or SWU policies due to licensing issue. All other policies are properly delivered as expected.
Verify if the solution licenses are installed correctly and not expired prior to contacting Broadcom/Symantec Technical Support.
